Tried a few great beers recently, sorry if they've already been mentioned:
Troeg's Mad Elf pretty good holiday ale
Hitachino - tried this over the weekend, a japanese made belgian white ale. Amazing, really made Blue Moon seem like Budweiser.
Opa - Opa holiday ale. Great beer made in Southampton MA
LAstly, and my favorite of the bunch is Monk's Blood. I have recommended it to many friends and they all had the same reaction when trying this ale: "Wow! that is great!"
Would Highly recommend.
